 receiving a first data message sent by the terminal and intended for said application server and/or a second data message generated by the application server or the network server and intended for the terminal; and 
 sending said received first and/or second data messages. 
 
     
     
       3. The transmission method as claimed in  claim 2 , wherein the obtaining comprises receiving the first authentication data, said first authentication data being transmitted by the management server. 
     
     
       4. The transmission method as claimed in  claim 2 , wherein the first authentication data are obtained in response to a message sent by said transmission device. 
     
     
       5. The transmission method as claimed in  claim 2 , wherein the act of establishing said session comprises:
 receiving a request to connect to said application server sent by said terminal, said request containing second authentication data; 
 sending, in response to said connection request, a message accepting connection to said application server comprising third authentication data, said third data comprising at least one item of the first authentication data and/or data generated by the transmission device. 
 
     
     
       6. The transmission method as claimed in  claim 5 , wherein the first authentication data comprise a primary key, the second authentication data comprise a first random value and the third data comprise a second random value, and wherein the method comprises generating a secondary key by applying a predefined function to said primary key, to the first random value and to the second random value. 
     
     
       7. The transmission method as claimed in  claim 6 , wherein the transmitted session establishment data comprise said secondary key. 
     
     
       8. The transmission method as claimed in  claim 6 , wherein the second random value is generated by the transmission device. 
     
     
       9. The transmission method as claimed in  claim 6 , wherein the third data comprise an address of the terminal generated or received by the transmission device. 
     
     
       10. A management server able to communicate with a transmission device via a gateway equipment forming a node of a telecommunications network and a network server of the telecommunications network, the transmission device being able to communicate via a radio link with the gateway equipment forming a node of a telecommunications network, wherein the management comprises:
 a processor; and 
 a non-transitory computer-readable medium comprising instructions stored thereon, which when executed by the processor configure the management server to perform acts comprising: 
 receiving establishment data for a communication session established between the transmission device and a terminal configured so as to connect to an application server via the network server; said communication session being established using at least one first item of authentication data obtained by the transmission device, the first item of authentication data being associated with at least one identifier of the terminal; and 
 commanding, following the reception of said session establishment data, recording of information relating to the established session in association with the identifier of the terminal in a memory accessible to the network server. 
 
     
     
       11. A management method implemented by a management server able to communicate with a transmission device via a network server of a telecommunications network, wherein the method comprises:
 receiving establishment data for a communication session established between the transmission device and a terminal configured so as to connect to an application server via the network server, said communication session being established using at least one first item of authentication data obtained by the transmission device; 
 the first item of authentication data being associated with at least one identifier of the terminal; and 
 commanding, following the reception of said session establishment data, recording of information relating to the established session in association with the identifier of the terminal in a memory accessible to the network server.
